Which protocol is used by presence-enabled users in Cisco IM and Presence to control phones that are registered to Cisco Unified Communications Manager?
Answer options:
A. AXL/SOAP
B. CTI/QBE
C. SIP/SIMPLE
D. LDAP
E. XMPP
Answer correct:
B
The CTI gateway provides desk phone control when users are configured for phone association mode. Proper installation calls upon information to specify CTI gateway server names, addresses, ports, and protocols on CUPS. Configured correctly, the CTI gateway enables users logging in to CUPC to reach the CTI gateway.
